When subscribing to assets for alarms and events, the viewing and acknowledgement of those alarms can be secured by the asset path. This provides a more intuitive way to secure alarms for users who rely heavily on assets.
This setting can be configured in the Workbench under Assets > Product configuration > Alarms & Events settings > General settings and subscriptions called Modify SourceName to start with Equipment or Property point name. This setting is enabled by default. When it is enabled, the SourceName field of alarms subscribed via AssetWorX is modified to include the equipment or property name.
An example SourceName would be:
ac:Alarms/Plant Area B/Sub Area A/:0:@ICONICS.AlarmSvr.1\Valve1.Limit.Condition
Including the asset name like this allows the Alarms tab of users or groups in security to properly match alarms with the asset tree. It would be possible to deny users the ability to acknowledge alarms under "Sub Area A" by denying them ac:Alarms/Plant Area B/Sub Area A/* on the Alarms tab.
